I have developed "tennis elbow" from lugging this book around the past four weeks, but it is worth the pain, the effort, and the aspirin. It is also worth the (relatively speaking) bargain price. Including appendixes, this book contains 894 pages of text. The entire panorama of the neural sciences is surveyed and examined, and it is comprehensive in its scope, from genomes to social behaviors. The editors explicitly state that the book is designed as "an introductory text for students of biology, behavior, and medicine," but it is hard to imagine any audience, interested in any fragment of neuroscience at any level of sophistication, that would not enjoy this book. The editors have done a masterful job of weaving together the biologic, the behavioral, and the clinical sciences into a single tapestry in which everyone from the molecular biologist to the practicing psychiatrist can find and appreciate his or

Principles of Neural Science

The mammalian ionotropic glutamate receptor family encodes 18 gene products that coassemble to form ligand-gated ion channels containing an agonist recognition site, a transmembrane ion permeation pathway, and gating elements that couple agonist-induced conformational changes to the opening or closing of the permeation pore. Glutamate receptors mediate fast excitatory synaptic transmission in the central nervous system and are localized on neuronal and non-neuronal cells. These receptors regulate a broad spectrum of processes in the brain, spinal cord, retina, and peripheral nervous system. Glutamate receptors are postulated to play important roles in numerous neurological diseases and have attracted intense scrutiny. The description of glutamate receptor structure, including its transmembrane elements, reveals a complex assembly of multiple semiautonomous extracellular domains linked to a pore-forming element with striking resemblance to an inverted potassium channel. In this review we discuss International Union of Basic and Clinical Pharmacology glutamate receptor nomenclature, structure, assembly, accessory subunits, interacting proteins, gene expression and translation, post-translational modifications, agonist and antagonist pharmacology, allosteric modulation, mechanisms of gating and permeation, roles in normal physiological function, as well as the potential therapeutic use of pharmacological agents acting at glutamate receptors.

The narcotic antagonist naltrexone has a biphasic effect on the nicotinic acetylcholine receptor.

The effects of intraarterially administered succinylcholine (SCh), acetylcholine (ACh), nicotine, DMPP and muscarine on acutely denervated muscle spindle afferent nerves and endings were compared. In order to characterize the role of dose and fiber types, at least four doses of each substance on each of 23 or more individual muscle spindle afferent units of a variety of conduction velocities were determined.

SCh, nicotine, DMPP, and ACh produced excitation of all spindle afferents examined, whereas muscarine caused a transient or longlasting decrease in afferent discharge frequency.

The magnitude of the increase in discharge frequency produced by SCh, nicotine, and DMPP was a function of the conduction velocity of the fiber of the afferent unit: the greater the conduction velocity the greater the degree of excitation. The major differences among the units were the consequence of the higher slope of dose-response curve of the more rapidly conducting afferents. On the faster fibers (Group Ia) SCh and nicotine were of the same order of potency.

Extrafusal neuromuscular block was also assessed: SCh was approximately 120 times as potent as nicotine; ACh was even less potent than nicotine. Muscarine was without detectable influence on the muscle twitch.

It is concluded that the excitatory cholinergic agents (ACh, SCh, DMPP, nicotine) have different sites and/or mechanisms of action in causing stimulation of muscle spindle afferent activity.
